3yo breathing squelchily and has been awake coughing much of the night - but breathing easier and sleeping a little now since coughing up some clear yellow liquid out of his lungs. Pretty sure it's bronchitis and he needs some antibiotics. Given that he is at last asleep my instinct is telling me to let him sleep and get an urgent appt at the GP when they open at 8:30 but am I being unreasonable - should I wake him and bundle him into the car to be seen more quickly at A&E?
